Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “find-salt19-tool”: FREE START-HERE ROUTER. Describe the fresh external fact, live state, developer intelligence, or bounded decision you need. Returns the best.”
“Use “salt19-pricing”: FREE catalog/pricing surface. Returns current discoverable SALT19 products, live x402 prices, schemas, and Fresh-State acquisition roles so.”
“Use “base-token-allowance”: Read a live ERC-20 allowance on Base for an owner/spender pair without an API key. Returns the current block and raw token units. Price: $0.”
“Use “base-token-balance”: Read a live ERC-20 token balance on Base and return raw units plus best-effort token decimals/symbol metadata without signup or an API key.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how SALT19 Agent Utility Grid holds up.
Operated by SALT19 Agent Utility Grid (salt19.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If SALT19 Agent Utility Grid adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose SALT19 Agent Utility Grid in the gate directory. No sign-in needed.
SALT19 Agent Utility Grid's tools are live in every AI client you've connected — with rules and logging built in.
